FIRESTOP SPACERS: (3600FS-8DM)
Firestop spacers are required at each point where the chimney
penetrates a floor or ceiling joist space. Their purpose is two
fold; they establish and maintain the required clearance
between the chimney and the combustible materials.
They also provide complete separation from one floor space to
another floor or attic space as required by most codes. When
penetrating a floor or ceiling at an angle, part 30FS-8DM
firestop should be used.
When the double wall pipe passes through a framed opening
into an attic space, the firestop must be placed into the attic
floor as in figure 6a.
When the pipe passes through a framed opening into a living
space above, the firestop must be placed onto the ceiling from
below as shown in figure 6b.
SUPPORT SECTIONS: (12S-8DM)
The chimney support section is a 4-strap 12” length of pipe. A
chimney support is required at the 30-foot level above the
fireplace after a straight chimney run (figure 7). This support
is designed to relieve the extra weight load on the fireplace
and elbows when high chimneys are installed.
PENETRATING THE ROOF:
To maintain a 1-inch clearance to the pipe on a roof with a
pitch, a rectangular opening must be cut.
STEP 1: Determine the center point through which the pipe
will penetrate the roof.
STEP 2: Determine the center point of the roof. Pitch is the
distance the floor drops over a given span, usually 12 inches.
A 6/12 pitch means that the roof drops 6 inches for each 12
inches one measures horizontally down the roof.
STEP 3: Use the roof opening chart below to determine the
correct opening length and flashing required (see figure 8).
STEP 4: Remove the shingles around the opening measured
and cut out this section.
STEP 5: Add the next sections of the pipe until the end
penetrates the roofline. Check to see that the proper
clearances are maintained. Extend chimney by adding
sections of double wall pipe until pipe is a minimum of 30
inches above the highest point of the roof cutout. Termination
and chimney must extend a minimum of 36 inches above the
highest point where it passes through roof (see figure 11).
FLASHING INSTALLATION: (6F-8 or 12F-8)
Determine the flashing to be used with the roof-opening chart.
Slide flashing over pipe until base is flat against roof. Replace
as many shingles as needed to cover exposed area and flashing
base. Secure in position by nailing through shingles.
DO NOT NAIL THROUGH FLASHING CONE.
STORM COLLAR INSTALLATION: (SC1 or SC2)
Place storm collar over pipe and slide down until it is snug
against the open edge of the flashing. Use SC1 for all round
and chase terminations and SC2 for all terminations with slip
sections.
Apply waterproof caulking to all seems and notches around
storm collar and also at base around shingles.
